To all whom t may concern:

Be it known that I,'FREDERICK S. DUEsEN- BERG, a citizen of they United States, vand a 'resident of Elizabeth, in the county .of

Union and State of New Jersey, have 1nvented an Improvement in Motor Vehicles,

vof which the following description in connection with the accompanying drawings,

is a specification, "like/characters on thedrawings -representing like parts.

This invention relates to motor vehicles, and aims to provide an improvedflexible mounting of the power plant on the chassis frame to prevent distortions of the latter from bein transmitted to the power plant, wihile sti permitting Ithe convenient re- Imoval of the under side of the crank-case,

and the crank-shaft, without the necessity of disturbing the mounting of the power plant.

My invention will be best understood by reference to thejollowing description, when taken in connection with the accompanying drawings `of one specific embodiment thereof, while its scope will be more particularly pointed out in the appended claims.

In the drawin s:

Fig. 1 is a an of the front portion of a motor vehicle exemplying my invention;

Fi 2 is a front elevation of a portion of the c assis frame and the motor at an en'- larged scale;

ig. 3 is a sectional View on line 3-3 of 2; and f ig. 4 is a sectional viewvat an enlarged scale on linea-4 of Fig. 1.

Referring to the drawings, and tothe embodiment of my ,invention which is herein selected for exemplication, I have shown a portion of a motor vehicle. having a chassis frame comprising a pair of longitudinal side members 6 and a cross member 8, the latter being adjacent the forward end of the frame. Any usual or suitable power plant, herein comprising an intern-al combustion engine or lmotor 10 and transmission gear set 12, is appropriately supported adjacent its rear end as by arms 14 projecting laterally from 'and conveniently formed as integral parts of the u per part 16 of the engine crank-case, said larms being suitabl attached to the side members 6 as by bo ts 18 which secure them to brackets 20, the latter in turn being secured to the side members as by rivets 22.

drains back' into the crank-case, whence it\ passes toan oil pump (not shown), which delivers the oil to the various bearings of the engine. The front end of the crank-case about the crank-shaft is herein'clos'ed by an under cap 28- and a front plate 30, which.

may be removed in obtaining access to the crank-shaft for ,the purpose of dismountng the latter.

It is well known that tortion, which is a t to be transmitted `to the power plant, an cause distortion of the latter, unless the same is iexibl supported on the frame. The character o the iexible connection should bev such that relative movement of the frame-and motor will take place about the axis ofthe crank-shaft; otherwise the axis of the latter may be shifted laterally when the frame becomes distorted. It has been proposed to rovide a mounting giving this desirable result, but heretofore thecharacter of such' mountings has been such as-to interfere with the removal of the crank-shaft, or at least to make the dismounting of the latter inconvenient. Sometimes, dso, the construction of these mountings has made it inconvenient' or impossible to obtain access to the gearin which transmits power from the crank-'sha t to the-cam-shaft and their accessory shaft or shafts. .These undesirable features are avoided in the mounting which will now` be described.

To the' end that relative move-ment bethe chassis frame of a motor vehicle 1s subject to more or'less disi tween the frame and thel motor shall take place about the axis of the crank-shaft, vI have herein provided an arcuate mounting in which one of the parts is provided with a surface 32 which is formed on an arc of' a circle struck from the axis of the crankshaft as a center. This surface is herein wholly above the axis of the crank-shaft, 1..

convenient removal of the front cover-platev4 4v30 and the cap-28, without the neceity off disturbing the mounting. In the present example, there are two superposed parts 3,4

and 36, one of which is conveniently formed `as a flange projecting from the front end of the upper side 16 of the vcrank-case, and the other as a flange on a bracket 38 suitably formed onor secured to the cross member 8. In this example, the bracket 38 is provided with a second flange '40 which overlies and rests upon the upper'side of the cross member 8. The bracket may be conveniently secured to the cross member by rivets 42 and 44;.

'Suitable means are provided to retain the flange 34 in place upon the flange 36, wh1le still permitting one to turn with relation to the other about the axis of the crank-shaft, such means conveniently comprising one or more, herein two, bolts 46 extending through both flanges, one of the latte-r, herein the flange 36, being provided with openings 4.8, which receive the bolts and permit a certain amount of free play of the latter. ably the connection between the two flanges j is resiliently yieldable in a vertical direction, thereby to permit a slight separation of the flanges when extreme distortion of the frame takes place; and to this end, I have rovided helically coiled springs 50 encircling the bolts. One end of each spring bears against an abutment, herein a nut 52 threaded onto the latter, while the other end of the spring rests against one of the flanges, herein the upper flange 34. The location of the springs above the flanges 1s preferred, because the working space about the forward end of the crank-shaft is much greater than if they were arranged below the flange. Another important advantage of the described mounting is that the cross member 8 does not re uire to be curved or offset in a downward 'rection Its central portion is therefore at a considerable distance above the axis ofthe crank-shaft, and presents no substantial interference with the work of dismounting the latter.

Having thus described one embodiment of my invention, but without limiting myself thereto, what I claim and desire by Letters Patent to secure is:

1. In a motor vehicle, the .combination of a frame having a pair of side members, a motor support supported b said side members and presenting an arc like, segmental portion, and a motor having one end supported by such portion with its shaft substantially Vconcentric therewith and mounted to turn about the axis thereof.
